Taschenbuch. Condizione: Neu. Neuware - Stop guessing why your tube amp sounds the way it does. Design it.Tube amplifiers reward the builders who understand them and punish the ones who copy circuits without knowing why they work. Designing Valve Guitar Amplifiers Handbook takes you from the physics of the tube to a complete, working 50-watt design. Every value is calculated, and nothing is left to rules of thumb.Inside, you will learn how to: - Read tube characteristic curves and set operating points with load lines- Predict stage gain, impedance, and frequency response before you pick up a soldering iron- Build preamps, tone stacks, and phase inverters, and understand why overdrive happens- Size push-pull output stages and specify the output transformer- Apply negative feedback without instability- Design power supplies, heater circuits, and grounding that stay quiet- Add effects loops, reverb, tremolo, and power scaling- Test, measure, and troubleshoot safelyWhy this book is different: - A single reference amplifier runs through the book, so every chapter builds on the last- 15 in-depth chapters with 30 original figures- Fully worked examples in every chapter- Practice problems with complete answers- Safety guidance throughout, because the voltages in these amplifiers can kill- A glossary, equation appendix, reference tables, and index for quick lookupWritten for engineering students, working engineers, and serious builders, the book assumes no prior tube knowledge, only basic algebra and circuit theory.Your next amplifier deserves better than trial and error.

Taschenbuch. Condizione: Neu. Neuware - One bad trench can end a job, a career, or a life. This manual shows you how to build every one of them right.Underground utility work is unforgiving. The ground shifts, the water rises, the bid margin is thin, and the inspector is watching. Pipe and Excavation Contracting Manual gives you the working knowledge to lay pipe safely, on schedule, and at a profit.Keith Y. Johnston covers the whole job in 16 practical chapters, from reading the plans to final commissioning: - Trench safety and shoring: soil classification, protective systems, and dewatering, explained so you can act on them in the field.- Pipe installation: materials, bedding, gravity sewers, storm drains, water mains, and force mains, with the checks that keep joints tight and grades true.- Trenchless methods: boring, jacking, and directional drilling, and when each one pays off.- Estimating and cost control: quantities, production rates, and bid pricing, built up step by step with worked examples.- Project management: scheduling, change orders, claims, risk, and environmental compliance.Every chapter opens with clear learning objectives. It includes worked examples, practice problems with answers, and 30 original figures. A full glossary, conversion tables, and an index make this a manual you will keep open on the tailgate, not shut on the shelf.Ideal for: - Contractors and estimators sharpening their bids- Superintendents and foremen running crews- Construction management and civil technology studentsStop learning these lessons the expensive way.
